If you are like most computer users, you have probably run across an error sometime or another when you are trying to open a file on your computer. Often times these files that give you the unknown file type error are attachments that you receive from emails or files that you download from the Internet.

The reason that you are seeing these file type or unknown file type errors on your computer is because the program or application that was used to create and edit that file you are trying to open is not installed and available on your computer. There are a lot of times when people will send you attachments and files in an email and they used a certain program to create the file, but when you try to open it you can not access it and instead all you get is an unknown file type error.

When you receive this file type error, you sometimes have the option to find or locate either on the Internet or on your computer a compatible program or application to attempt to open the file with. The reason that this is such a common error is because there are literally thousands of file extensions available, and in some programs and applications, there are even different file extensions for different versions of the program or application. File extensions are used to help denote what kind of file it is. For instance, when you see a .dot file extension, you can assume that it is some kind of document file and that it requires some kind of word processing program to open and read it. There are a lot of different kinds of word programs available for computers, and depending on what kinds and what versions you have on your computer, you may not always be able to view and read those files. Usually what happens is that your computer searches for a compatible program or application to use to allow you to view the file, although some kinds of formatting are usually lost along the way.

To help determine why you are getting unknown file type errors, look at the file extension to help you determine what kind of program it is. There may be simple downloads or programs that you can use to help you open the file. If you are getting the unknown file type error often, or if you know that you have a compatible program that should be able to open and read the file but it is not, there may be a problem on your computer. To help prevent these kinds of errors and problems from occurring, it is always a good idea to perform clean up on your registry and to do maintenance on your registry and your system. There can be many kinds of errors that can occur if you have a virus on your computer, so always be careful when you are opening and downloading unknown files on your computer. You also may be seeing file type errors if your computer feels that the file type may not be safe to open. This can occur if you have anti-virus software installed or if you have your security settings set high on your computer. You may need to alter these in order to allow a program or application on your computer to access and open the file.
